Samsung Galaxy Nexus & Ice Cream Sandwich Review
by Brian Klug & Anand Lal Shimpi on January 18, 2012 1:34 PM ESTThe Keyboard
The stock Gingerbread keyboard was a significant step forward, but the ICS keyboard is really good. I don't know that there's much that's truly groundbreaking about the ICS keyboard, but it's at the point where short of Swype for those users who care about it, I would be very disappointed to see any third party keyboard replacements from HTC, Motorola or Samsung.
The basic layout hasn't changed from Gingerbread, although there are a few subtle differences. You get the same standard four row keyboard with two alternate modes (numerics and symbols). Where the Gingerbread/ICS keyboards differed from the standard iOS or Windows Phone keyboard is there's a fifth row of punctuation keys by default above the rest of the keyboard. This fifth (or first, depending on how you look at it) row actively changes into a list of predicted words. The word in the center is what the autocorrect engine believes you're typing, while the words on the left/right are alternates. While Gingerbread allowed you to scroll horizontally on this row, the items are fixed in ICS. As a consolation, you can bring up additional autocorrect suggestions by tapping and holding on a word in the prediction row. Accented characters are available by pressing and holding on keys that can be accented. Popup menus also exist for punctuation and the smiley key.
Keypresses are still accompanied by a magnified duplicate of the key itself. Unlike in Gingerbread where the magnified key hovered unconnected, the ICS keyboard connects the magnified key to the key itself. In my opinion this makes the keyboard look less chaotic when you're typing very quickly. Rather than giving the impression of random letters flying around everywhere, the animation serves its intended purpose better: letting you know what you just hit.
There's also a hidden Android Keyboard debug settings pane with some different themes that can be selected.

Android has historically offered multiple options to secure your phone or tablet. Ice Cream Sandwich continues the trend. You can choose a basic PIN with a minimum of four numbers and a maximum of 17. There's an alphanumeric password option, simple slide to unlock and no security at all. ICS adds a new option to the list: Face Unlock.
The feature is exactly what it sounds like. ICS can store a photo of your face and use it as authentication for unlocking your device. While you only need a single picture to start, Google recommends taking multiple photos in different lighting conditions, with/without glasses and with a clean vs. unshaven face if applicable. As a backup you have to provide ICS with a PIN in case it can't recognize your face (either due to lighting conditions or because of a recent tumble down some stairs).
Google warns that someone who looks like you would be able to unlock your device, making Face Unlock less secure than a long PIN, pattern or password. Admittedly a thief would have to either be really lucky or know what you look like to fool the technology, but it is a valid point.
The feature actually works surprisingly well in practice. With Face Unlock enabled the lock screen has a front facing camera live view window that you're supposed to use to center your face. With the exception of really bright (with the light shining into the camera) or really dim scenarios, Face Unlock worked for me almost every time. When it works perfectly using your face to unlock the phone is extremely quick. In the right conditions I've seen ICS unlock itself a split second after I even saw my face on the screen. On average though the process is slower than typing in a PIN or using any of the other unlock methods. Furthermore, if you use your phone a lot at night (especially in cars) you have to hit the power/lock button then tap the lock icon to circumvent Face Unlock and go directly to your PIN/password/pattern. Finally, don't try to use Face Unlock to unlock your phone while driving - that's a recipe for bad, or worse, death.

I think it's already been mentioned that 4.03 fixed the task switcher lag. I have alpha ICS 4.03 roms running on a Nexus One, Nook Color and Samsung Galaxy Tab 10.1 and everything runs very smoothly on all 3 devices. Even the very underpowered Nook has surprisingly little lag and stutter when using the task switcher and transitioning between screens/app drawer etc.Chloiber - Wednesday, January 18, 2012 - link
The Galaxy Nexus is a very nice phone indeed, but there are just some things that I don't like about it. As mentioned in the review, the GPU is not the best, which is actually the main reason I won't buy the phone. I buy smartphones which should last about 2 years. Buying one with a GPU from the beginning of last year is just not good enough. As Anand mentions: better wait for Q2, maybe Q3. At the moment, the GN is certainly the best phone (in my opinion) money can buy, but it's not the right moment to buy an android phone.The review is very late indeed...but very thorough - thank you!
One question remains: are microSD slots a thing of the past? Google mentioned that there is a good reason why they didn't include one (slow speeds for apps). But I still think that's a very bad reason not to include a slot. While it is true, that the mSD cards are pretty slow compared to internal storage, there is just no way in hell I'm gonna pay 100$+ for 16GB of additional internal NAND. Additionally, you don't need high speeds for music, pictures and movies (the main reason to get an SD card).
I hope for a phone in Q2/Q3 with a) better SoC, b) an SD card slot and c) a 720p IPS or SAMOLED+ screen.

I agree. The GPU is a terrible oversight on this phone, particularly considering the inclusion (finally) of OpenGL rendering throughout Android.With the 4S GPU being 3-4x faster it's tough to see how this phone is going to stand the test of time. Presumably the iPad3 and next iPhone will be packing an even more powerful SoC and GPU.
This is one of the main reasons that I think Apple is in a great position going forward with regards to hardware. With the exception of Samsung, everyone else is relying on TI, Qualcomm, Intel, etc to make the right decisions with regards to CPU/GPU etc combination and clearly those chip makers do not always have the best insight with regards to product pipeline or requirements.
A retina display-ish version of the iPad is going to take a GPU far beyond anything the current SoC guys are manufacturing.

The next generation of PowerVR SGX graphics chips are supposedly 20x as powerful as the current ones. I'm guessing Apple will still be using the dual core variant of the 6** series. That's good, if the 4x screen resolution rumours are true.Yeesh, Android devices still haven't caught up to the old GPU now a new one is around the corner. Nvidia is stuck with their own GPU's of course, but TI or Samsung should switch to PowerVR if this performance domination continues.

What performance domination?! Android phones are easily the most powerful on the market!Greg512 - Wednesday, January 18, 2012 - link
Not when it comes to GPU power. The iPhone 4S has a GPU 3-4 times as powerful as the one in the Nexus. Android phones do tend to have higher clocked processors, however, so they do have a healthy advantage on that front. Android phones also have more RAM, though many would debate that iOS is memory efficient, negating the hardware advantage.KoolAidMan1 - Wednesday, January 18, 2012 - link
You're kidding, right? The Tegra 3 is slower than the eight month old A5. Everything in Android world is playing catch-up with old parts, which is odd given that they have a more frequent upgrade cycle. Problem is that they've been behind since the beginning.doobydoo - Thursday, January 19, 2012 - link
trob6969 - the leading Android phones have CPU's which are largely comparable to the CPU in the iPhone 4S - in some cases they even boast up to ~10% extra performance (as a result of, in some cases, 50% higher clock speed), but only in CPU limited tasks, and that <10% is barely noticeable.Graphically, the GPU in the Nexus Prime is far slower than even the Samsung Galaxy S2 - using an older GPU which is up to 3x slower than the GPU in the iPhone 4S. The GPU in the SG2 (the fastest Android GPU) is also far slower than the iPhone 4S (as the benchmarks in this review show)
Because iOS is hardware accelerated (and tightly intertwined with the iPhone), the performance of the iPhone 4S and iOS is far superior to any Android phone out at this moment in time.
zorxd - Thursday, January 19, 2012 - link
uh?50% faster clock speed gives you 50% more performance in CPU limited tasks. Don't forget that it's the same architecture (Cortex A9).
I hope you are not making that 10% claim based on javascript bencmarks. They are browser benchmarks more than CPU benchmarks.
Zoomer - Thursday, January 19, 2012 - link
Not really, the A9 ISA have many different architecture implantations. TI does their own, Apple probably did their own, and I believe nVidia has their own too.
